speedvision camshaft

[srferreras]

good night. some have experience with Speedvision cams? I put on my 5efe turbo and I have a very IDLE something. at 1300 rpm and vacuum 10.'s this normal?

[Chief Quimby]

Did you time everything, or just put them on the marks.

Running them too, and had almost same problem.

[RobSR]

Loads of people had problems with them when they were first released. Down to the fact they are just poop and terribly made.

I run a set from the first batch and they run fine. If a little noisy but il put that down to the shims.

Were the first batch not fine and the. He sourced a cheaper manufacturer for the 2nd batch that went horribly wrong

[Ryan-11]

Yeah the second batch were awful, the inlet cam was machined wrong, the cam gear locating pin was in the wrong place, replacements were sent out but i never trusted mine in the end.

I worry about the vacuum that is always in 10Hg to 1200rpm. 1000rpm unless it gets in 5Hg

[Chief Quimby]

Well, you have to mesure them with micro meter Watch( think it is call), i put mine on 108 degres at 1mm lift.

I dyno it at 396hp at 1,85 bar, som i would say they Work just fine.

wath degree (grade) used in variable pulley

[Chief Quimby]

When you buy cams, there is supose to be som specifacation on them. There is not on those speedvision, so i did them, something near 2jzgt, because they have almost same stroke. I am running adjustebel camgear too

Could be interesting to know, what orther people with speedvision cams did, and what degree with 1mm lift, or they just installed them, and wondered why they didnt work

Hey there you danish starlet freak

getting some more speedvision cams for my next engine.

last time i had them i just fitted to the marks check the shims and drove it (with mapping etc)

What specs and insight can you offer into what exactly you did? i want to be able to get the most out of these cams as possible.
